Abstract:
Objective:To investigate the clinical characteristics,pathological features,treatment,and prognosis of clear cell adenocarcinoma of cervix(CCAC).Methods:Clinical data of 72 CCAC patients treated at Jiangxi Maternal and Child Health Hospital from January 1,1999,to June 20,2024,were retrospectively analyzed.Results:The median age at diagnosis was 50 years.Of the patients,19 were classified as early-stage(IB1,IB2,IIA1),51 as mid-advanced stage(IB3,IIA2-IVB),and 2 were unstaged.Among 38 patients,elevated cancer Antigen 125(CA125)levels were observed in19(50.0%).Abnormal thin-layer liquid-based cytology(TCT)results were de-tected in 14 of 20 patients(70.0%),and human papillomavirus(HPV)positivity was identified in 20 of 45 patients(44.5%).Immunohistochemical analysis revealed hepatocyte nuclear factor-1β(HNF-1β)positivity in 95.2%and paired box gene 8(PAX-8)positivity in 91.3%.Among 32 patients undergoing primary surgery,postoperative pa-thology confirmed pelvic lymph node metastasis in 5(15.6%),lymphovascular and stromal invasion in 9(28.1%),with no ovarian metastasis observed.With a median follow-up of 45 months,the5-year overall survival(OS)rate was 51.4%,with early-stage and mid-advanced stage OS rates of 57.9%and 47.1%,respectively.The 5-year OS rate for surgically managed patients was 52.8%,while preoperative neoadjuvant chemotherapy(9 cases)yielded a 5-year OS of 33.3%.Among38 patients treated primarily with radiotherapy and/or chemotherapy,the5-year OS was 47.1%,with 5 patients undergoing central lesion resection achieving an 80.0%5-year OS.Conclusions:CCAC predominantly affects middle-aged and elderly women,with advanced-stage presentations being common.HPV,TCT,and CA125 testing hold diagnostic value for CCAC.Patients with early-stage CCAC undergoing surgical treatment demonstrated a relatively favorable survival rate;however,individualized assessment remains essential.Neoadjuvant chemotherapy administered prior to surgery may have limited efficacy in improving patient prognosis.For selected patients completing radiotherapy and/or chemotherapy,central lesion resection may potentially im-prove prognosis,although further well-designed studies are required to validate this finding.
